The Saskatchewan Teachers' Federation has notified its 12,000 members of the province-wide walkout, the Canadian Broadcasting Corp. reported Saturday.
The union said none of its members should report to work Wednesday and Thursday.
The union held a one-day strike May 5.
Contract talks broke down Thursday. The federation is seeking a three-year contract with a total 16 percent raise while a committee of provincial officials and school trustees says Saskatchewan cannot afford more than a 6 percent raise over three years.
